' ,"Z'o (tZZ 1.0720711, it may concern.-

"to which the front end of 'oted.

The frame is made with two sides, which are duplicates, connected by'an overhead Be it known that 1, PETER PAUL HARlNG, a

citizen of the United States, residing at Goliad, in the county of Goliad and State of Texas, have inventedcertain new and useful Improvements in Cotton-Picking Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to cotton-pickin g inachines of that class in which the cotton-boll is caught onthe end of a. revolving picker.

The main feature of my inventiomconsists of the combination of a revolving drum carried on a suitable frame and provided with fixed radial tubular arms set in the sides of the drum, the said tubular arms having on their sides, also set radially, hollow nipples carrying revolving pickers.

My invention also includes detail of con struction and subordinate features and combinations, as hereinafter-fully set forth, and all as illustrated in the accompanying drawings, in Which I v Figure 1 shows the machine in .planv view with part of the upper frame removed. I Fig. 2 shows a rear view-with vertical belts omitted. Fig. 3shows a side elevation. Fig. 4 shows a part of one of the drums in Vertical sectionlwith some of the arms in position. Fig. 5 showsa cross-section of one of the arms, with the picker in its nipple. Fig.6 is a longitu-dinal section of one of the arms, and Fig. 7 shows the arm in another longitudinal sec-. tion.

It will 'he observed thatthe parts are en.- larged in some of the figures.

In the drawings the main frame is shownv as supported on Wheels A B, of which E B are in the rear and directly support the frame, the front wheels AA, Fig. 1, being on a truck,

the .frame is pivtransverse part of the frame. Thevertioal parts of the frame are shown at a and the transverse parts at b.

Mounted in the frame .are vertically-arranged drums 3, the shafts of which have their hearings in the frame. These drums are arranged in pairs, one on each side, and maybe one or more pairs. 1 have shown two. The drums of each pair are side hyside in the frame, and the pairs are so arranged that they straddle a rowof plants and cause the plants of the row to pass between the pairs of drums as the machine advances.

The machine advances in the direction of the arrow 1, Fig. 1. The drums turn toward each other, as shown by the arrows 2,-and the plants aredrawn in between the arms.

The drums are caused to revolve by means of a sprocket-chaimd, engaging with sprookets on the drum and moved by sprocketwheels D on shafts e, geared to the rear axle,. .as shown 'in' Fig. 3.

The drums therefore run loose on their shafts c, which are turned by jzn'eans of sprocket-Wheels fiwhich are connected to like wheels f f on the shaft e. Through these shafts motion is communicated to other shafts g, mounted in the heads of the drums, throughgears H h. Small pul leys 5 on these shafts drive the picker-spindies 6. These shafts g are located opposite the vertical rows of arms I, which extend ra.

dially. The arms I are also arranged in horizontal rows, as shown in Fig. 3, and the arms of opposite drums interlock .sufiicientl-y to cover all the space between thedrums, they being set so that the vertical rows of one drum followa vertical row of the opposite drum of the pair. The'horizontal rows of arms are placed at a distance intended to allow the bollsto pass between adjacent rows, and no more.

Within thearms is the driving belt or cord 7, as'shown in Fig. 4. 'Itengages with p111- leys 8, fixed centrally on the picker-spindle 6, which has its bearing in hollow nipples 9, .fixed in the walls. of the larmsl. 'lhese'nippies are set in rows, one on the upper and one on the lower side of each arm,,the said rows extending from near the"drum to near the end of the arm and so arranged that every boll asit passes between the arms shall be 1 caught by a picker. The pulleys 8 are held between the inner ends of the nipples, and the spindles turn in the nipples. On the outer ends of the spindle are teeth of any desired shape adapted to catch the cotton. -I prefer to make these as shown m'ore clearly in Fig.

' dles are very loosely set in-the nipples, so that there is a considerable free space in the nipple about the spindle, also that the outer ends of the nipples are beveled on the inner edges and rounded on the outer. I have foundthat the inner bevel and the loosely-set spindle" preven tt lie cotton from binding and choking the spindle. Thaba-nd or rope may be carried under and over the pulleys 8, as shown in Figs. 4 and 7. The nipples and picker ends project slightly from the arms, as shown in Fig. 4=, for example, and as the arms are carried with the revolution of the drums they take the bolls met by the machine in its forward movement,and thes'e'bolls are compelled to pass between said arms. The pickers, kept in rotation at the points when the arms meet the bolls, catch onto thecotton and by twisting up.over'the points firmly grasp and pull the cotton from the boll and carry it aside as the drum turns. I

After the arms have carried the cotton to the outside of the machine it is in position to be dropped upon a traveling belt or carrier. In order to prevent stalks or empty-bolls from passing into the space over the carriers,

I set bars 9' in the framework in the frame- The carrier is shown in Figs. 2 and 3. In.

Fig. 3 is shown the longitudinal carrier,

which is an endless belt 10, carried on drums 11 and 12. There is one of'these belts on-each side outside of the drum-shafts and directly under the outside half of the drums, where' the cotton is dropped. These carriers have suitable teeth to catch the cottonand. carry it forward to a vertical carrier 10, of similar construction, and mounted on drums 13 and 14K.

This carrier delivers the cotton to the pocket 70, as shown clearly in Fig. 3. The drum 11 is driven by sprocket connection with the rear axle, and the drum,12 is geared to the drum 13, so that the motion .of the firstof the machine and the carriers 10 on both sides.

discharge into it from separate openings 1.

In order to release the cotton from the pickers, on which some part of it is twisted, it is necessary to arrest the rotation of the picker-' spindles. For this purpose the beveled gear 77. on the upper end of the shaft 9 is splined,

so that it can be lifted, and as the drum turns to bring'any given vertical row of pickerarms to the outside from the carrier the gear;

mal driving mechanism. For the better release of the cotton from the picker I prefer .to give a reverse turn to the picker-spindles,

and this is done by causing the gear h on the bevel-gear, as it is raised, to engage with the segment at, toothed to engage with the gear h. This slight reversemotion is given to the gear h, while the belt 10 is endless, and it is carried on the drums 11 and 12.
